Remove intra doc link items if they are private/hidden and the matching option is not enabled

[GuillaumeGomez]

Fixes #130233.

Since such items cannot be linked to, there is no point in keeping them as candidates.

Some more investigations about how to add this check: I need to have cache.paths and cache.external_paths to be filled. However the Cache::populate code is called after the intra-doc link pass. So I first moved the intra-doc link pass after it, but then some random things break. So seems like I'll need to keep running the intra-doc link pass before, keep all alternatives around and then after the Cache has been populated, I'll be able to filter items.

Implemented the approach I described above. Hopefully should fix all issues now. :)

Ignored the rustc lint. I also realized that in case there were still unresolved intra-doc links, I wasn't emitting an error. It's now fixed with two new ui tests to ensure it. :)

If you're running `tidy`, try again with `--bless`. Or, if you just want to format code, run `./x.py fmt` instead.
